28edd79d64 8145221: Use trampolines for i2i and i2c entries in Methods that are stored in CDS archive
This optimization reduces the size of the RW region of the CDS archive. It also reduces the amount of pages in the RW region that are actually written into during runtime.

97e169ac77 8145628: hotspot metadata classes shouldn't use HeapWordSize or heap related macros like align_object_size
Use align_metadata_size, align_metadata_offset and is_metadata_aligned for metadata rather than align_object_size, etc.  Use wordSize rather than HeapWordSize for metadata.  Use align_ptr_up rather than align_pointer_up (all the related functions are ptr).
